Fattening up my sound with the G major

[Themetallikid]

I'm looking to use the Pitch setting to add some thickness by adding voices a few cents + and - of my original signal.

 

What are some settings to start with?

 

I know its all to my ear, but I have no idea where to start for thickening up a clean, crunch and heavy distortion settings, and a lead as well. Will the settings differ for each amount of gain or delay in my sound?

 

Thanks for any help.
